COOLING SYSTEM Russian patent published in 2019 - IPC F27D9/00 F27D1/12 F27B1/24 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used for cooling of metallurgical furnace lining. Cooling system includes cooling liquid supply unit, cooling unit of cooled object, communicating with cooling liquid supply unit by means of cooling liquid supply pipe, coolant return unit includes cooling fluid return pipe group and coolant return tank. At that, coolant return pipe group includes coolant liquid return pipe and suction pipeline. Cooling liquid return pipe connection pipe from suction pipeline is interconnected with cooling unit, suction pipeline channel from coolant return pipe is communicated with cooling fluid return tank. Group of pressure pumps includes an injector and a pressure pump, wherein the injector is interconnected with the delivery pump and is located on the suction pipeline in a communicating manner.

EFFECT: invention allows preventing spill of cooling liquid, even if cooling unit has leakage, as a result it is possible to reduce risk of potential hazardous situations and reduce resistance to liquid flow.
